You will get an automated Gemini API workflow for your business
Project details
Are you trying to automate your business with AI, but struggling with unreliable text blobs and hallucinations? Basic ChatGPT wrappers aren't enough for enterprise needs. You need structured, deterministic AI workflows.
As a Senior Full-Stack Architect, I build robust Generative AI pipelines using the Google Gemini API and NodeJS. I enforce strict JSON schemas so the AI outputs exact, predictable data that syncs flawlessly into your database.
From automated content generation to complex RAG (Retrieval-Augmented Generation) setups that read your private company data, I engineer systems that don't just chat—they work. Send me an Upwork message today to discuss your AI architecture.

WordPress Theme / Site Speed Expert
Krunal is the best freelancer I’ve worked with in 8+ years. It's immediately clear that he's an expert in his field, and he went far above my job requirements to ensure I was satisfied with every aspect of his work.
Krunal's task was to improve my website speed, and he took my Google Lighthouse speed scores up to 90+ (on mobile) and 95+ (on desktop) on virtually every page. He asked thoughtful questions throughout the project to ensure he was making the right decisions, and at the end of the project, we had a 30-minute call where he explained all of the changes he made and answered my questions about those changes.
I am extremely satisfied with Krunal's work and will hire him again whenever I get a chance. If you have the opportunity to work with Krunal, you will not be disappointed.

About Krunal
Senior Full-Stack Architect | GenAI (Gemini) | Angular/React | Node.js
Vadodara, India - 4:28 am local time
I spent the last 10 years fully dedicated to that role as Technical Lead — heads-down, shipping, not bidding on Upwork. I'm opening up capacity for new projects again now, bringing current, production experience in Node.js, React, Angular, and Google Gemini-powered AI features straight from active enterprise work.
⚙️ WHAT I DO
• Architecture & Leadership — Full SDLC ownership: database schema design, code quality standards, and delivery management for distributed teams.
• Enterprise Platforms & LMS — Built and scaled internal operational hubs, SaaS scheduling systems, and large LMS platforms, with multi-tier RBAC for different employee and learner roles.
• Generative AI Integration — Production use of the Google Gemini SDK and AI Studio for automated content engines, adaptive testing tools, and AI-assisted curriculum generation.
• Legacy Modernization — Migrating monolithic systems into decoupled, type-safe architecture without halting feature delivery mid-transition.
• Performance & Infra — Serverless via Firebase, background job processing with BullMQ/Redis, server administration (WHM/cPanel, SSL).
🛠️ TECH STACK
Frontend: Angular, React, TypeScript, Tailwind CSS, PWA
Backend: Node.js, Express, PHP (Laravel, Slim)
Data: PostgreSQL, MySQL, Firestore, Redis, BullMQ
AI / Cloud: Gemini API, Google AI Studio, Ollama, Firebase, Cloudflare
If you need someone to map out the architecture, own the backend logic, or both — send me what you're building. I'll give you a direct, specific read on scope within a few hours, not a generic pitch.

Architecture & Prompt Engineering
I will analyze your data flow and engineer highly calibrated system prompts using the Gemini API to ensure precise, hallucination-free responses.
NodeJS/PHP API Integration
I will build a secure backend microservice to handle the AI payload, enforce strict JSON schema validation, and manage rate-limiting.
